Question

The hormone which is antagonist to the insulin is

• A. Thyroxine
• B. Glucagon
• C. Calcitonin
• D. None of the above

Answer 1

The correct option is B Glucagon

Glucagon and insulin are peptide hormones produced by alpha and beta cells of the pancreas respectively. Glucagon raises the concentration of glucose in the bloodstream. Its effect is opposite to that of insulin, which lowers the glucose concentration. The pancreas releases the glucagon when the concentration of glucose in the bloodstream falls too low and insulin when the concentration of glucose in the bloodstream increases.

Thus, the correct answer is option B.
